Nuclear terrorism in an ex-cold-war armoury: terrorists plan to arm and detonate the stored warheads, and the bomb sites sit deep in the munitions store. Outside the winter lake skybox closes over concrete and snow; inside are storage halls and service corridors. Sixteen spawns per side and two bomb sites.

A custom map rather than a retail one: Barney built it in about two weeks plus a few days of playtests, in Worldcraft 3.3 compiled with ZHLT. The custom textures came from Gearbox Software, Frank Nuccio and RzE of CS-Nation ran the playtesting, and the name came out of a CS-Nation naming contest won by Skinner. All 50 textures are compiled into the .bsp — 8810 faces in a 4576 × 4704 × 1360 unit volume, against de_dust2's 5383. The archive installs the .bsp, the snowlake skybox, the flare sprite, the radar overview and a .res file.
